WASHINGTON (Reuters) – Two Americans with ties to Gambia were part of a failed effort last week to overthrow the tiny West African nation’s government, the U.S. Justice Department charged on Monday.

Cherno Njie, 57, and Papa Faal, 46, a former U.S. Army sergeant, will appear in federal courts in Baltimore and Minneapolis on Monday, the department said. The two men have been charged with conspiring to carry out the violent overthrow of a foreign government, it added.
